Centipede is working

I received a working AR-II board from a KLOV member this week and had a chance to install it in my Centipede. I fired it up and it had some horizontal sync issues. After about 15 minutes of fine tuning it, Centipede now works! I am a bit concerned about the h-sync not staying as I had to re-adjust it about 2 hours later and it also has lost the color red. I keep troubleshooting it, but I'm guessing the monitor is due for a cap kit...
